* fix(keyframes): report unresolved GSAP timing instead of guessing rest poses
* fix(keyframes): drop later times when a delay cannot be resolved
Boolean(null) treated an unreadable delay as no delay,
so the next cursor-relative tween kept a guessed start.
* fix(keyframes): keep a staggered rest pose in Studio
The parser stops are what Studio holds, so a staggered from keeps its rest
pose there. The CLI reports that pose as unresolved, and an unread position
no longer seeds the next tween at zero.
